Twenty-five years ago, the Kitchen, the lauded sound institution, made history with its pioneering music festival New Sound, New York, bringing new American artists like Philip Glass, Meredith Monk, Laurie Anderson, and Steve Reich from downtown lofts to uptown auditoriums. The Kitchen, in collaboration with the Irwin S. Chanin School of Architecture of the Cooper Union (and 11 other arts organizations), explores the nexus of sight, sound, and space with an amazing six-week citywide expo. The fest brings together some of the original downtown sound explorers with new artists and organizations in performances, lectures, and installationseverything from interactive electronic-art pieces, three-dimensional sound structures, and listening rooms to an ambitious sound installation transforming the waterfront of the World Financial Center. This week offers acclaimed minimalist composer Philip Glass and maverick architect Thom Mayne in a dialogue on music and architecture on Wednesday; a feedback-driven production with Alvin Lucier, James Fei, Jim O'Rourke, and friends on Thursday; and a sound installation by Israeli composer Amnon Wolman from Saturday through April 24. Watch for more in the coming weeks, especially the not-to-be-missed April 27 Kitchen benefit concert featuring elder statesmen of the avant gardeAnderson, Glass, Monk, Reich, and othersall on one stage.
